Scope of Work

• Design of primary and secondary circuits for 32 substations
• Procurement
• Sampling of oil from old equipment and analysis for PCB (Polychlorinated Biphenyl) content
• Primary circuit equipment for 32 substations
• Secondary circuit equipment for 4 stations (Ulaanbaatar TPP, CCH-4, Erdenet TPP, Darkhan TPP)

Project Summary

This project aims to improve the reliability of Mongolia’s Central Energy System (CES) by replacing outdated and faulty equipment at 32 substations with modern technologies, thereby reducing power outages and operational failures. The old equipment, which has been in use for many years, not only increases the risk of system disruptions but also contains accumulated harmful PCB (Polychlorinated Biphenyl) substances, making its replacement essential to meet environmental and safety standards.

Funded through a concessional loan from the Government of Germany, the project will replace primary equipment at 32 substations and upgrade secondary systems at 4 substations. These improvements will enhance energy efficiency, stabilize electricity transmission, and strengthen the overall reliability of the CES network.
